Phys.org / Tiny Jurassic bird reveals a key step in bird evolution
The transition from a lumbering, heavy dinosaur body to the flight-adapted bird body plan is one of many fascinating episodes in evolutionary history. Working out how this massive transformation took place relies heavily ...
Phys.org / How Fourth of July celebrations and the national political mood may shape psychedelic experiences
Psychedelic drugs are known to make people highly sensitive to their surroundings. In other words, a user's mindset and immediate environment heavily shape the entire trippy experience. In a study published in the journal ...
Phys.org / Evidence of elusive high-energy gravitons in quantum Hall systems
Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective excitations referred to as quasiparticles. One case in which this occurs is the quantum Hall effect, a ...
Phys.org / Greenland meltwater adds to AMOC weakening, but updated model finds no tipping point in sight
The state of the Atlantic Meridional Overturning Circulation (AMOC) has been a hot topic among climate scientists in recent years. The AMOC is crucial for climate regulation because it pulls warm surface water from the tropics ...
Medical Xpress / Families report positive outcomes from fully virtual, BCBA-delivered, focused autism support program
A new study, conducted by AnswersNow in partnership with the Clemson Center for Behavior Analysis (Clemson University) and published in JMIR Pediatrics and Parenting, finds that fully virtual applied behavior analysis (ABA) ...
Phys.org / This rare British butterfly looks familiar, but its genome tells a very different story
The British swallowtail butterfly (Papilio machaon britannicus) is the U.K.'s only native swallowtail and its largest native butterfly. It's instantly recognizable by its striking light yellow-and-black wings, with twin tail-like ...
Phys.org / The oldest deliberately collected fossil ichthyosaur was discovered in Roman Britain around 1,800 years ago
Around 1,800 years ago, a fossilized spinal bone lay on the windswept beaches of Roman Britain until a curious passerby picked it up and carried it far away, only to drop it in a pit.
Phys.org / Rare color shifting discovered in iconic Australian frog
University of Newcastle researchers have documented one of the clearest examples of iridescence ever recorded in an amphibian, revealing that the endangered green and golden bell frog (Ranoidea aurea) possesses intricate ...
Tech Xplore / Light-powered chip harvests energy, computes and senses chemicals in one stack
Most contemporary portable electronics, including laptops, smartphones and smart watches, are powered by batteries that need to be recharged daily or every few days. Over the past decade, however, some engineers have been ...
Science X / Could endless scrolling really rot your brain? A new study suggests it might, but also says exercise could fight back
Consider flipping through numerous videos on TikTok within mere minutes—some news item, some dancing fad, some culinary trick and some comedy sketch. The content might grab your attention momentarily, but it's gone just like ...
Phys.org / Why Europe's trees are dying
In Europe, trees are increasingly dying prematurely. A new study by the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) on French forests now shows that it is not only drought but also unusually warm ...
Phys.org / New CRISPR method makes it possible to control protein production in cells
The speed at which a cell produces proteins is a decisive factor in determining whether it divides, specializes or retains its stem cell properties. A team of researchers led by Professor Stefan H. Stricker, professor of ...
